Title: Magnetron driving and controlling circuit
Inventor: OZAWA SEI
IPC: H05B6/68
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To safely use a magnetron by suppressing a rush current since even when a triac is turned off by opening a door to turn off a door switch in order to stop the operation of the magnetron, next when the triac is turned on, the polarity of a commercial power source becomes reverse to that when the triac is turned off. SOLUTION: When a door is opened, a malfunction preventive circuit 12 receives the OFF signal of a door switch 9, and a relay driving power source 11 is cut off, thereby turning off a relay driving circuit 6. A latch circuit 13 does not turn off the relay driving circuit 6 immediately when the door switch 9 is turned off and the off signal of the door switch 9 is not inputted to the malfunction preventive circuit 12 so as to wait until a triac 5 is turned off by a microcomputer 10. Next, when the triac 5 is turned on, the microcomputer 10 ascertains the polarity of a commercial power source and when the triac 5 is turned off, the polarity is inverted, thereby controlling a rush current into the triac 5.

Title: Semiconductor memory
Inventor: KAJI NAOTO
IPC: G11C11/413
Filed: 1990-09-25
Abstract: PURPOSE:To facilitate a performance discrimination at the time of writing by applying an independent clock not to be used normally to a write pulse generating circuit, and setting the timing of a write pulse optionally. CONSTITUTION:First, at the normal operation, a line 104 (a clock A) is used to fix at a value '0'. At this time, if a write request is the value '1', the value '1' is set in a write request register 4, and the write pulse (a line 115) is generated. And if the write request is the value '0', a line 112 becomes the value '0', so the line 115 turns to the value '0' as well, and a write is suppressed. Next, at a function testing time, a clock B (a line 105) is used. In this case, if the write request (a line 103) is the value '1', a write pulse generating circuit 5 generates the write pulse by the edge of the clock B inputted from a line 114. At this time, if the timing of the clock B to the clock A is set, for example, faster by a DELTAt, the write pulse is shifted by the DELTAt from the normal.

Title: Wire disconnection detector
Inventor: KOMINATO KAZUAKI
IPC: G01R31/02
Filed: 1988-10-11
Abstract: PURPOSE:To detect the occurrence of abnormality and to stop a machine before a wire disconnection is caused by using at least one of the shafts of >=2 rotary pulleys as a moving shaft. CONSTITUTION:A strand 1 passes rotary pulleys 2a and 3a, and then 2b and 3b. The pulleys 2a and 2b are supported by the moving shaft 4 and the pulleys 3a and 3b are supported by a fixed shaft 5. Further, the moving shaft 4 is suspended from support shafts 6a and 6b fixed to the fixed shaft 5 through a spring 7 which balances with the constant tensile force of the element wire 1. When an abnormal tensile force is applied in normal operation, the pulleys 2a and 2b are closed so as to balance with the tensile force of the spring, thereby using a stored wire. Further, a reflecting plate 8 is fitted to an end of the moving shaft 4 and when a constant position is reached, light emitted by a photoelectric tube 9 strikes on the reflecting plate 8 and the stop circuit for the machine operates. Then the remaining stored wire is fed until the machine stops completely through the operation of the stop circuit to eliminate the possibility of a wire disconnection.

Title: Coating method of micro-body surface with metal oxide
Inventor: ITO SEISHIRO
IPC: C23C22/02
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and homogeneous coating film of a metal oxide by dissolving a metallic salt in an organic solvent, adding a micro-body thereinto, dropping an organic solvent containing a hydroxide ion and after dropping, refluxing. SOLUTION: A salt containing the desired metal. oxide is dissolved in the organic solvent having polarity at first and after that, the micro-body having a functional group on the surface is added. And the organic solvent containing the hycdroxide ion is dropped under stirring. At this time, though the metallic ion M becomes a colloid particle of a metallic hydroxide and gradually grows, the colloidal. particle exceeding a certain size becomes unstable because of the reaction in the organic solvent. When the colloidal particle meets the micro- body P having negative charge on the surface, both are rapidly combined with each other as shown by the arrow and the surface of the micro-body P is coated with the metallic hydroxide. After the dropping is finished, the metallic hydroxide is converted to the metal oxide with the heat by refluxing and the desired coating is obtained.

Title: Etching method
Inventor: TAJI SHINICHI
IPC: H01L21/302
Filed: 1986-10-29
Abstract: PURPOSE:To enable the quick and high-precision formation of a groove large in an aspect ratio, by using halogen or simple substance gas and etching a matter to be etched under specific conditions. CONSTITUTION:Gas, in which C and Si are not contained and at least one species of F Cl, and Br is contained, is used and an Si substrate 31 is etched to obtain a groove by keeping such a temperature that probability of reaction of F, Cl, Br in the plasma to surface elements on the substrate 31 is one tenth or more as large as the probability of reaction at 20 deg.C. A resist film 30 is used as a mask in order to perform this etching. When P is contained in the etching gas, a temperature of the substrate is made -60 deg.C or less. When Cl is contained there, the temperature of the substrate is made -40 deg.C or less. When Br is contained there, the temperature of the substrate is made -10 deg.C or less. Because Si and C are not contained in the etching gas, there is no deposit on the surface of the substrate during an etching operation and so the etching speed is increased in the direction in which the substrate becomes deeper. Hence, the processing time for this deep groove processing can be shortened.
